Can lme or lmer fit a plain regular fixed effects anova? Ie a model without a
random effect, or have there be at least one random effect in order for these
functions to work?
Trying to run such, (1) without specifying a random effect produces an error,
(2) specifying that there is no random
Hi all:
I can use the density() function to get the kernel density for given
observed data X with bandwidth.
Is there a function in R that can take in two dimensional data(x, y) and
return a joint density based
on the bandwidth. Do I need to provide bandwith for x and then for y?
Is the GRASS
D'Oh!
yet again my first inclination is to write something complicated when a
little thought shows a short, neat solution. Ah, well, I live and learn.
Cheers,
Simon.

?gls in package nlme. It's like lme but with no random effects. But you
can still model the variance-covariance properties of the data.

Hi,I obtained the ect term from cajorls in urca. I found a result that would
like to obtain some explanation here. My setting is that I have 2 variate time
series. I use ca.jo to perform Johansen test. 1. I found that sometimes, in the
case where the ca.jo test statistics suggest that I have 1
Hi, I found kde2d in the MASS packages return densities for the bivariate
random varaibles.
I donot understand why each element of density Z is a 2*2 matrix.
Why it is not a number.
For example, a bivariate normula distribution given (x, y) will return a
number, the density, not a matrix.
Also, look at options(digits) to set the number digits to be printed in
the console, i.e.
pi
[1] 3.141593
options(digits=22)
pi
[1] 3.141592653589793

Hi Ross,
In brief, you can use ggopt(aspect.ratio = 1) or p$aspect.ratio - 1
to set the aspect ratio for all plots, or for a single plot
respectively. There are a few example of this at
